FIG. 1-2 is a plan view in which spherical surfaces are alternately embossed on the upper and lower sides of a spacer film, and a sectional view taken along line bb' below. FIG. 1-3 is a plan view of a spacer film embossed with a zigzag sawtooth waveform, and cross-sectional views taken along lines aa' and -bb' at the bottom and right. FIG. 2-1 is a plan view of a spacer membrane with many diamond-shaped holes formed into a reticular membrane. Figure 2-2 is a plan view with sawtooth waveforms along the intersections of the meshes of the reticular membrane in Figure 2-1, and side views from two directions, vertical and horizontal, are shown to the right and below. . FIG. 2-3 is a plan view showing pulse waveforms along the intersections of the meshes of the reticular membrane in FIG. 2-1, and side views from two directions, vertical and horizontal, are shown to the right and below. Figure 3 shows an example in which, when making a large number of circular holes in the spacer film, four claw-shaped parts are left on the edge of the circle, and these claw-shaped parts are alternately bent up and down to protrude from the spacer film surface. A perspective view of. FIG. 4 is a perspective view of a laminated insulation material using a spacer embossed with the zigzag sawtooth waveform of FIGS. 1-3 as a spacer. 1... Reflective film, 2...

Claims

[Claims for Utility Model Registration] (1) The space between the inner container for keeping cryogenic objects cold and the outer container surrounding it is made a vacuum, and metal such as aluminum is placed on one or both sides of the vacuum space. In a laminated insulation material for cryogenic temperatures that uses reflective films made of vapor-deposited plastic films and spacers that prevent contact between the reflective films and minimize heat conduction between the reflective films, they are alternately stacked.
A spacer for a laminated heat insulating material that has a plurality of high parts and/or low parts relative to the plane of the spacer film, and expands the space between the reflective films and reduces the contact area between the reflective film and the spacer. (2) The spacer according to claim 1, wherein the high part and/or the low part with respect to the plane of the spacer film is provided with a large number of embossments on one or both sides of the film. (3) Scope of claims for utility model registration in which the high and/or low parts relative to the plane of the spacer film are formed into a net by forming a large number of holes in the film, and the reticular spacer film is corrugated to provide high and low parts. The spacer according to item 1. (4) The high and/or low parts relative to the plane of the spacer membrane are created by punching a number of holes in the spacer membrane, leaving claw-like parts at the edges of the holes, and bending these to the top and/or bottom to provide the high and low parts. A spacer according to claim 1 of a certain utility model registration.
